SANJOAQUIN Environmental Health Department COUNTY- 6. Email notification to ust(a)smqov.orc1 to arrange the following inspection appointments. All appointments must be scheduled at least 48 hours in advance. INSPECTIONS PRIOR TO BACKFILL a) Inspection of tank vacuum gauge or for brine leaks prior to tank placement in excavation. b) Verification of tank set, anchorage, appropriate backfill,and appropriate additional corrosion protection of tank anchors(turnbuckles,eye bolts, etc.).Additional corrosion protection is required on all exposed metal prior to backfill. c) Primary tank test, in accordance with manufacturer specifications. d) Primary piping test: Soap test of all piping joints and penetrations (product, vapor recovery, vent, and chase), and pressure testing —hydrostatically at 150% of design operating pressure or pneumatically at 110% of operating pressure. If the calculated test pressure is less than 40 psi, 40 psi shall be used as the test pressure. Testing must be conducted in accordance with manufacturer specifications and California Code of Regulations (CCR) Title 23. e) Secondary piping test: Soap test of all piping and penetrations (product, vapor recovery, vent, and chase), and pressure test, in accordance with manufacturer specifications. f) Verification of secondary piping slope for all piping (product, vapor recovery, vent, and chase) at 1/8 inch per foot or greater, to a containment sump with an audible and visual alarm. Piping slope must be adequate at the start of this inspection, with all piping in its final position and ready to be backfilled without adjustments per the manufacturer's installation instructions. g) Verification of all pipe setbacks, cross-overs, and burial depth, in accordance with manufacturer specifications, and verification of appropriate piping backfill. h) Integrity testing of all sumps, in accordance with manufacturer specifications. i) Verification of brine type, and witnessing of initial brine addition in all brine-filled sumps and/or LIDCs. INSPECTIONS PRIOR TO FIRST FUEL DELIVERY j) Verification of leak monitoring communication for all installed vacuum, pressure, or hydrostatic(VPH) components, including piping, sumps, under dispenser containment sumps (UDCs), and all chase lines. Communication at end points of each vacuum zone and each vacuum monitored sump must be verified independently in operating condition. k) Verification of the dispenser footprints contained by the UDCs. Any potential leaks from piping and fuel filters must drain directly into LIDCs. 1) Enhanced Leak Detection (ELD) testing, after facility is in operating condition. Appropriate test notification and tester certifications are required. Passing ELD test results must be submitted to the EHD within 60 days of testing. ELD test results must be received by the EHD before written approval to deposit fuel will be issued. m) Verification of liquid and vapor tightness component installation (shroud boots and band clamps for spill containers, appropriate rubber-type gasket or clamps on lids on all fill, vent, and STP sumps, etc.). n) Verification of overfill prevention: Measurement of drop tubes to verify 95% tank volume shut off, verification of external audible/visual alarm activation when tank is 90%full, or other approved method. o) Spill bucket test: Verify minimum 5-gallon capacity. Pass a one hour hydrostatic test (or equivalent). Verify proper drainage method. p) Monitoring system functionality: Functionality of the monitoring system, including all liquid and vacuum sensors, must be verified to ensure it meets the requirements of CCR Title 23 and California Health & Safety Code (HSC) Chapter 6.7. 2 of 4
